A narration on fitnah in Sham

Imam Nu’aym ibn Hammad (rahimahullah) has recorded this as the statement of Sa’id ibn Al Musayyab (rahimahullah) and not as a Hadith of Nabi (sallallahu ‘alayhi wa sallam). This chain consists of a narrator who has been declared weak by some Muhaddithun and very weak according to others.
